*1 Execute the I/O verification operation by selecting ntlp??? Options
the CX-Programmer.
*2 A404.00 to A404.07 contain the error slot number (00 to 09) in binary. "0F hex" indicates that the slot cannot be deter-
mined.
"0B hex" indicates a bus error occurred for the built-in EtherNet/IP port.
"0E hex" indicates the End Cover is not connected to the CPU Rack or an Expansion Rack.
*3 The CJ1W-ID201 (8-point DC Input Unit), CJ1W-OC201 (8-point Contact Output Unit), CJ1W-IA201 (8-point AC Input
Unit), CJ1W-OA201 (8-point Triac Output Unit), and CJ1W-OD201/202/203/204 (8-point Triac Output Units) are allocated
one word each, so set them as 16-point Input Units or 16-point Output Units in the I/O tables when manually setting the
I/O tables from the CX-Programmer. An I/O setting error will occur if they are set as 8-point Input Units or 8-point Output
Units.
*4 Regardless of the error that occurred, the three bits in parentheses will be stored in A407.13 to A407.15. The value will
simultaneously be stored in A407.00 to A407.12.
*5 Bits A410.00 to A410.15 correspond to unit numbers 0 to F.
*6 Bits A411.00 to A416.15 correspond to unit numbers 0 to 95.

A403: Mem- An error has occurred in memory. A
ory Error bit in A403 will turn ON to show the
Location location of the error as listed below.
A403.00 ON: A checksum error has
occurred in the user program mem-
ory. The power was turned OFF while
storing data to the flash memory
(backup memory).
A403.04 ON: A checksum error has
occurred in the PLC Setup.
A403.05 ON: A checksum error has
occurred in the registered I/O tables.
A403.07 ON: A checksum error has
occurred in the routing tables.
A403.08 ON: A checksum error has
occurred in the CPU Bus Unit Setup.
A403.10 ON: An error occurred in
flash memory (backup memory).
A293 The user program that was trans-
ferred includes functions that are not
supported by the unit version of the
CPU Unit.
--- When A401.03 is ON: The contents
of the Memory Card cannot be cor-
rectly read to the CPU Unit when the
power is ON.
--- FALS(007) has been executed in the
program. The error code in A400 will
indicate the FAL number. The left-
most digit of the code will be C and
the rightmost 3 digits of the code will
be from100 to 2FF hex and will corre-
spond to FAL numbers 001 to 511.
Probable cause
See below.
Check the program and correct the error.
Clear the entire PLC Setup to 0000 and reenter the
settings.
Initialize the registered I/O table and generate a new
I/O table.
Initialize the routing tables and reenter the tables.
Initialize the CPU Bus Unit setup and reenter the
settings.
CPU Unit hardware is faulty. Replace the CPU Unit.
• Check whether the unit version supports the user
program.
• Upgrade the unit version of the CPU Unit.
Check whether the files required for executing the
automatic transfer function are available.
Correct according to cause indicated by the FAL
number (set by user).
